Suppose X is a citizen of two countries, A and B, both of which permit dual nationality. Should they obtain both passports and renew both of them when about to expire?

    "Should they obtain both passports and renew both of them when about to expire?" It's completely up to them. Only if they want to. It's obviously more work and may cost something but may also offer greater flexibility. In the end, the decision will be a compromise and highly specific to personal circumstances.

    I voted to close this as opinion based because of the word "should," but on reflection I would say it is rather too broad, because it entirely depends on the countries involved.

    I cannot understand why anyone would not renew and keep up to date all passports to which they are entitled. Countries can fall apart quickly. Suppose you wanted to flee a civil war or invasion but Country A did not want to let its citizens leave; they'd probably allow a citizen of County B to leave rather than upset Country B. Country B might not be accepting refugees, but if you hold one of its passports, they'll let you in. Over the lifetime of a passport the cost is negligible.

  • I'm thinking of reworking the question along the lines of "What are the advantages and disadvantages of obtaining and renewing both passports?". Would that improve the question, by making it less opinion-based? Most of the existing answers would fit that question. Commented Nov 3, 2017 at 4:13

    @Flynn renewing passports costs money and time, as well as the aggravation of dealing with bureaucracy. The cost is small, but so may be the benefit: the chance of capitalizing on the benefit you contemplate in the event of a civil war or invasion is very small indeed, although it does vary according to the countries involved.

If X can possibly afford the fees, it is much better to hold actual passports for both nationalities.

A country may require the use of its passport by its citizens when entering or leaving the country. The US is an example, although the practical penalty appears to be a delay and lecture.

On the other hand, some countries require the mandatory use of its passport by its citizens when at least entering the country. e.g. X wants to visit country A (and doesn't have country A's passport) and country A has visa requirements for country B citizens. In such a case X would need to obtain a country A visa on X's country B passport prior to travel. A real-world example is a dual US/PAK citizen traveling to PAK having just a US passport.

X may have a need to travel urgently to a country that permits visa-free travel for one of the passports, but not the other. The delay in either obtaining a visa or obtaining a passport after finding out about the need to travel may be inconvenient. In general, you cannot expect other countries to allow the travel benefits of being a citizen of country A unless you can present a country A passport.

Generally, not holding a passport does not exempt you from the obligations of a citizenship. For example, the US tax obligations of a US citizen are not affected by whether the citizen has, or has ever had, a US passport.

    I think some countries may refuse to give visas to their own citizens.

    @gnasher729 I think most countries refuse to give visas to their own citizens. (I know of a couple that will put a visa-like "endorsement" in foreign passports held by their citizens, but they carefully avoid calling those things visas.)

This hugely depends on the two countries involved. For example, if one of the countries requires you to enter and leave with their passport (like the US does) then it's a good idea to keep that passport up to date if you intend to visit that country. On the other hand, if both of the countries passports are accepted in most places, such as two European countries, then there isn't much benefit to holding two.

I have dual citizenship and stopped renewing one of them years ago. But a change of residence would make the one I dropped valuable, and I would switch.

    "Hugely depends" indeed. In the case of the Netherlands, for example, dual citizens who live outside the kingdom and outside the EU for ten years will lose their Dutch nationality, but can prevent this loss by getting a Dutch passport before the ten-year period elapses.

The big advantage to having both of your passports is that you can enforce your right of entry. As a citizen of a country, you have an unassailable right to enter that country. A non-citizen can be refused entry. If you don't present that country's passport when you enter it, you technically don't have the absolute right to enter, although many countries will give you the right if they can be satisfied that you are actually a citizen of theirs. A passport is pretty compelling proof of citizenship (obscure non-citizen passport situations excepted).

As mentioned by other posters, one passport may give you visa-free access to countries that the others don't, so you may prefer to use one passport over the other in some circumstances. On the other hand, if both your passports are EU Schengen-area passports, for example, there may be little advantage to having both, as you have right of entry into the Schengen area with either one.

  • See for australia (sydney.edu.au/news/84.html?newsstoryid=15178), which makes many references to international law, and convention. The the right to enter your own country is from being a citizen, not to having a passport. International laws are very weak. but in general impression I have got from: travel.stackexchange.com/questions/43903 and travel.stackexchange.com/questions/67110 and a few others is that you may be inconvenienced by not having a passport to prove your identity, that the actual right is attached to being a citizen and high-courts have maintained it.

  • @LyndonWhite The passport is an excellent proof of citizenship. If you can prove citizenship in other ways, that is probably sufficient. Unfortunately, a birth certificate proves nothing about citizenship, even in countries where being born there gives citizenship, since you can voluntarily give up citizenship. Commented Nov 3, 2017 at 14:14
  • sure, i agree that practically your passport give you your right of entry. but technically it is your citizenship. Which disagree with your statement that it is technically your passport. Commented Nov 4, 2017 at 0:03
  • @LyndonWhite I could rephrase it as something like that "you likely don't have irrefutable evidence of your right to enter" if you are not carrying a passport. Commented Nov 4, 2017 at 0:22

I know that there are some countries where failing to renew a passport under certain conditions means that you are no longer interested in citizenship, and citizenship will automatically be revoked.

For example, this is the case for citizens of the Netherlands who have dual citizenship and have not lived in the Netherlands for the past ten years. If they fail to renew their passport on time, their citizenship is automatically revoked.

I also recall hearing of situations where not renewing a passport will make life really difficult if you want to get that passport later on. I don't remember any specifics though.

I recommend checking citizenship and passport rules to ensure that not renewing a passport won't have any unanticipated consequences.


Many people live in one country and never leave it, even when they have citizenship in an other country. In that case it is very likely they do not want to have a passport for the country they do not live. In fact, many people do not even have one passport.

And in some cases it might be prudent not to be able to prove citizenship, like when you may be forced to join their army, even when you do not speak the language and have no ties (other than one of your parents having been born there) to the country.
Not having a passport may not be enough to avoid military service, but not having applied for a passport might make a difference in some cases.

    The point about the military duty (and proof of citizenship or lack thereof) is more complex than that. Singapore and Korea are good examples of this: you don't decide to hide or show your citizenship -- the country does. Singapore and Korea decide for you whether you're a citizen, and whether you're subject to military duty.

  • My mate C was born prematurely and unplanned in Poland. She always thought she was British, like her parents, until she got called up for military service when she was 18. If she goes to Poland she will be arrested for not doing this. Well, it's probably outside the statute of limitations by now.

Not unless they've a need.

There are certainly countries it's easier to get into with a passport for one of my citizenships than the other, and vice versa. Not having a pressing need to visit any of them, why would I waste money on a passport I'm not going to use?

If I was planning to visit a country that is more welcoming of the citizenship I don't have a passport for, I would certainly consider getting it (though probably not; the few places that would prefer it aren't particularly unwelcoming of my other citizenship either, but for other citizenships it can make a massive difference).

If I was expecting to have some need to prove that other citizenship for some reason, I'd probably get a passport.

If I was expecting to have to leave the country in a hurry (not a bad thing to assume as a possibility wherever one was) and the citizenships had very different treatments in many countries (in my case they do not), I'd consider having both.

I'm not going to spend time and money on a piece of paper that'll just get itself lost somewhere in my office though.


Just to give one concrete example of the potential benefits- a colleague has three passports (issued by three different countries, on three different continents). For visiting a certain country (Turkey) the cost of a visa is $60 US, $20 US or $0 US, depending on which of their passports they use. If they tried it with a US passport they would not be granted an e-visa at all.

The passport is usually just proof of a condition that already exists, so in most cases one would renew it if the document might be useful to you.

There are however possibly circumstances in which renewing or not renewing a passport conveys intent. This is more likely to come up with regard to refugee status and that sort of thing. In which case a qualified professional had better review the case with reference to the individual situation and countries involved.
